A couple weeks ago our dryer quit spinning the drum. I went to a couple of forums and everyone pointed to the motor. I bought a new motor and a new starter switch, just in case, and installed both. After installing these we can get the drum to spin only if you hold the start button in for about 20 seconds. If you put a load of clothes in the dryer, it will not start spinning. We actually opened the door, held the door switch down, held the start button down and spun the drum by hand and it worked.
I called a technician he looked at the dryer and said that I had a bad motor, I had just replaced the motor, so I ordered another motor, installed it and still have the same problem.
Symptoms;
You should not have to hold the starter button down for 20 seconds to start the dryer. It will not start spinning with a load of clothes in it. I have changed all electrical components except the timer.
I have checked voltage at the terminal block, plug outlet, etc, everything is good
PLEASE HELP I am at my wits end after two motors and two weeks of down time.
Problem should be either electrical or mechanical (too much drag on the motor).
I am assuming that the motor does not start and it is not that the motor runs but the drum does not turn.
When you said you checked the voltage, did you do a live test?
Pt one meter lead on X at the timer and the other on Neutral.
You should see half the line (120 volts).
Now push the start button.
The voltage should stay constant.
If it drops much then you have a power/wiring problem.
Best to do the above with two people as it is safer.
If the voltage is OK then it will be a mechanical problem.
Manually turn the dryer in the correct direction to see how much drag there is.
You may want to try this on a couple units to get a feel for it.
Also put some clothes in it to see if it increases.
Common problem areas are the rear drum support bearing (is at the bottom of section 03).
Check the plastic receiver part of it for wear.
Also be sure it is well lubricated with high temperature grease.
Check the front glide (item 24 in section 03).
Check the idler wheel (item 23 in section 09).
Check the front door seals.
